Aspinning top rotates so that its edge turns at a constant speed of 0.63 m/s. if the top has a radius of 0.10 m, what is the
centripetal acceleration of the edge of the top?
o 0.016 m/s2
0.73 m/s2
4.0 m/s2
6.3 m/s2

The  centripetal acceleration of the edge of the top

Explanation:

Given:

Speed with which the top rotates =  0.63 m/s

Radius of the top = 0.10 m

To Find:

Centripetal acceleration of the edge of the top =?

Solution:

The centripetal acceleration is the rate at which the tangential velocity changes. Also its direction is always inwards along the radius vector of the circular motion.

We know that centripetal acceleration is

Where

v = velocity

r = radius

Substituting the values

radial fractures in a piece of glass look most like which of the following?

a. spokes of a wheel

b. a circle

c. a zig zag

d. none of the above

the correct answer is a. spokes of a wheel

hope this (:
